There is more or less 7 millions of bitcoins currently in circulation. There is approximately 50,000-70,000 bitcoin users (if you take the number from mtgox and consider that people not on mtgox are balanced by the fake accounts).

Which means, on the average, 100bitcoin per user.

Still below average, discovered Bitcoin when it was around 10$. It's almost embarrasing how cheap you could buy those 100 BTC just a couple of months ago. Should've would've could've...

Well, I keep an history of all my transactions and it is embarrassing to see that I've bough a bunch of them at 0,72€ and sold them at 0,94€, thinking it was a huge opportunity, making 10€ benefit in the mean time ;-)
